Most important consideration in regard to this type of failure is capacity of metal to absorb energy; if elastic energy stored in metal exceeds energy required to propagate crack, brittle fracture is imminent, and even slight increase in stress, slowly applied, may cause failure; slower-acting forces such as expansion of corrosion products under hoops on masonry stacks, or of bricks in retaining shells, often result in brittle fracture, sometimes with disastrous consequences; two simultaneous conditions are necessary to cause brittle fracture in steel; these are high unit stresses, and brittle behavior of metal.
